[R] SJava

[Prof Brian Ripley]

You need to ensure that libRSNativeJava.so is in your LD_LIBRARY_PATH: 
last time I looked SJava came with scripts to achieve this, and I suspect 
you need to read the documentation about them.

As a further note, these are programming questions about a non-R product, 
and  R-help is _really not_ the appropriate forum.  Do please consult the 
posting guide.
